Daim ntawv thov

Praseodymium Hlau, yog siv los ua tus neeg sawv cev muaj zog alloying hauv Magnesium siv nyob rau hauv qhov chaw ntawm lub tshuab dav hlau. Nws yog ib qho tseem ceeb alloying tus neeg sawv cev hauv Neodymium-Iron-Boron hlau nplaum. Praseodymium yog siv los tsim cov hlau nplaum uas muaj zog heev rau lawv lub zog thiab kav ntev. Nws kuj tseem siv tau rau hauv lub teeb, taws teeb, 'flint thiab steel' hluav taws pib, thiab lwm yam. Praseodymium Hlau tuaj yeem ua tiav rau ntau yam duab ntawm ingots, pieces, xov hlau, foils, slabs, rods, discs thiab hmoov.
